JAMES SAWYER, OE FBE EBURG, ILLINOIS, ASSIGNOR OF ONE-HALF T WASHINGTON DE BOLT, OF ST. LOUIS, MISSOURI MINERS LAMP.

SPECIFICATION forming part of Letters Patent No. 268,944, dated December 12, 1882.

Application filed September 11, 1882. (No model.)

To all whom it may concern.-

Be it known that I, JAMES SAWYER, of Freeburg, St. Clair county, lllinois, have made a new and useful Improvement in Miners Lamps, of which the following is a full, clear, and exaot description, reference being bad to the annexed drawings, making part of this specification, in which- Figure 1 is a view in perspective of the improved lamp; Fig. 2, a view in perspective, showing the lamp attached to a miners cap; and Fig. 3, afront elevation of the cap.

The same letters denote the same parts.

A niiners lamp is usually suspended from his cap, the lamp being furnished with a hook consisting of a single piece of wire bent into the shape of an ordinary hook and engaging in a hole in the cap. Such a fastening is ob jectionable in this: the lamp cannot readily be attached, both hands usually being needed for the operation, and after being attached the lamp dangles in all directions, swinging both laterally and also toward and from the miners face, and occasioning annoyance and sometimes serious trouble; also, for the purpose of loosening the wick, the miner is in the habit of tapping the lamp at its lower front against some hard surface, causing the lamp to leak and wear out at the point in question.

To obviate these objections is the. aim of the present improvement, which relates partly to the means for attaching the lamp to the cap and partly to the means for protecting the lamp at its lower front.

A represents the improved lamp, and B the miners cap. G is a hook, in position and shape corresponding to the ordinary hook, saving that its point 0 stands out from the lamp farther than is customary, and so as to project beyond the plane of the hooksD E. Thehook C, while it can be used to attach the lamp to the cap, is not designed therefor, but for hanging up the lamp when not in use, or when not attached to the miners cap. The hook D is the improved means for attaching the lamp to the cap. The noticeable features of this book are its width and its tapering form. At its upper end, 61, the hook in practice is made nearly or quite as wide as the lamp, and from socket.

its upper end it preferably tapers downward to its point d. The hook is also preferably elastic. The hook is preferably made of wire bent into the form shown and described. The lamp is attached by inserting the hook D in a socket, F, of corresponding shape, in the cap B. The socket is preferably made by means of the facings G H, the facing Gr being attached to the cap, and the facing H being attached at its side edges, h h, to the facing G, the space between the facings forming the The lamp thus attached cannot swing outwardly from the cap, and by reason of the width of the book 1) the lamp cannot swing sidewise. The miner can thus hold his lamp much more steadily than heretofore. Another spring, E, is preferably employed in connection with the spring D. VVheu the lamp is attached to the cap the spring E bears against the outer side of the facing H. The spring E is narrowed at its point e, enabling the point to bear upon the facing H, within the wires h h, and thus bind the facing H to advantage and attach the lamp more securely to the cap. As a further precaution the coil-spring or other extensible band, I, may be used to secu:e the lamp to the cap. This hand I, at its ends, is attached to the cap or t'acings, and after the lamp has been hooked to the cap the band can, as shown in Fig. 2, be slipped upon the lower end of the lamp. The lamp at its lower front, a, is tipped with a protection-tip, J, which stands out slightly from the shell of the lamp. The miner, in tapping the lamp for the purpose described, strikes the tip against the wall, or whatever surface is used to strike against, and the lamp proper is thus preserved from wear. The tip J also forms a shoulder for holding the band I in place. It is not necessary to use the book 0; but when attached to the lamp and the lamp is attached to the cap the point of the book 0 passes through a hole, 0, in the cap or facing Gr. It is not essential, however, even when the hook O is used, to have it pass through the cap or facing.

I claiml. A miners lamp, A, having the hook D and the spring E, as and for the purpose described.
